An air-mass thunderstorm, also called an "ordinary", [1] "single cell", "isolated" or "garden variety" thunderstorm, [2] is a thunderstorm that is generally weak and usually not severe.

2021年6月9日 · Pop-up thunderstorms, also known as air mass thunderstorms, are common on summer days when a hot, humid maritime tropical (mT) air mass is in place. Anyone from the south is familiar with this air mass.

Air mass thunderstorms typically are associated with warm, humid air in the summer months; they develop during the afternoon in response to insolation, and dissipate rather quickly after sunset.

2005年8月17日 · In thunderstorm: Isolated thunderstorms. These storms are sometimes called air-mass or local thunderstorms. They are mostly vertical in structure, are relatively short-lived, and usually do not produce violent weather at the ground.

Air-mass thunderstorms are unaffected by frontal activity. They are usually scattered or isolated. Air-mass thunderstorms may be further classified as convective or orographic, although these lifting processes often act together.

Air mass thunderstorms typically are associated with warm, humid air in the summer months; they develop during the afternoon in response to insolation, and dissipate rather quickly after sunset.

Thunderstorms form when warm, moist air rises into cold air. The warm air becomes cooler, which causes moisture, called water vapor, to form small water droplets — a process called condensation. The cooled air drops lower in the atmosphere, warms, and rises again. This circuit of rising and falling air is called a convection cell. If this ...

Air mass thunderstorms most often result from surface heating. When the storm reaches the mature stage, rain falls through or immediately beside the updraft. Falling precipitation induces frictional drag, retards the updraft and reverses it to a downdraft.

2024年12月27日 · Thunderstorm - Updrafts, Downdrafts, Air Masses: The motion of a thunderstorm across the land is determined primarily by the interactions of its updrafts and downdrafts with steering winds in the middle layers of the …

2024年5月24日 · Air mass thunderstorms are usually created by convective uplift of warm, moist, and unstable air. Have you ever been surprised by a sudden downpour of thunderous rain on what was up to that point a pretty nice day? If so, it was probably an air mass thunderstorm.
